Abstract

PURPOSE: To keep the efficiency of pipe-line processing, by generating and storing an index set and continuously accessing operands only for index values included in the specified index set.
CONSTITUTION: A vector operation part 10 executes the operation of specified data, i.e., vector or matrix. An operand address calculating part 20 calculates an operand required for operation, i.e., the address of array in a data memory 11. An index calculating part 30 generates and stores an index set and is provided with an end discriminating circuit 41 and a positive/negative discriminating circuit 42. The end discriminating circuit 41 discriminates the index value of an operated result or read-out data and divides the discriminated results into a group having a specified property and a group having no specified property.
